Complexes [Ag(NH2R)2]X, (X = NO3, R = -C6H4-CnH2n+1-p, -C6H4-O-CnH2n+1-p, -CH2-C6H4-O-CnH2n+1-p, n = 6, 8, 10, 12, 14; X = BF4, R = -CH2-C6H4-O-CnH2n+1-p, n = 6, 8, 10, 12, 14; X = OAc, R = -CH2-C6H4-O-C10H21-p; X = CF3SO3, R = -CH2-C6H4-O-C10H21-p) have been prepared. They all show SA mesophases corresponding to two kinds of structures, already present in the solid state. The alkylaniline and alkoxyaniline derivatives adopt a bilayered structure where the cation has an extended centrosymmetric conformation. The benzylamine derivatives contain U-shaped cations giving rise to a bilayered structure which allows microsegregation of the organic part of the molecule from the inorganic Ag?(anion) part. Some degree of interdigitation of the terminal chains is observed for all the complexes with aryl containing ligands.
